Engineering math, twice a month.
One or two emails per month, written by Ishak. Engineering technique (Postgres patterns, Stripe edge cases, RAG in production) and engineering math (cost breakdowns, hire-vs-subscribe analyses). Occasionally a case study. Always specific.
Written by Ishak, founder of Stacklane in Groningen.
Three things that earn the inbox.
- 01
Engineering math, with the receipts
Cost breakdowns, hire-vs-subscribe analyses, the real numbers behind senior salaries in NL. The math that's usually hand-waved in vendor decks, shown in full.
- 02
Engineering technique, from production
Postgres patterns we use on real cases. Stripe edge cases we hit and fixed. RAG pipelines in production, not in tutorials. Code you can actually run.
- 03
Case studies, no slide ware
Occasional walkthroughs of what we shipped: the constraint, the trade-off, the integration we picked, the bill at the end. Same voice as the rest of the site.
Four things this isn't.
- A drip funnel
- We do not auto-fire seven emails over fourteen days. Each send is written when there's something to say. If we'd be padding, we skip the month.
- A sales sequence
- Subscribing is not a sales-call request. The booking CTA at the bottom of the welcome email is there if you want it; nobody chases you if you don't click.
- Three emails a week
- The cadence is one or two per month. If your inbox is sacred, this list will respect that. If you want daily content, follow the LinkedIn instead.
- A partner share-of-list
- Your address never leaves Resend's audience (EU, signed DPA). No co-promotions, no list rentals, no "sponsored by" sends. Documented on the trust page.

Sends are written by Ishak, founder of Stacklane. Same voice you'd hear on a discovery call: senior engineer, peer-to-peer, no marketing softeners.
